QAV-M 114 // Babyhawk rebuild

Despite it being pink, which is usually an instant win in my book, I was always slightly disappointed by my Babyhawk, largely due to the complete lack of camera protection (I broke the camera on literally the second outing). So I figured I'd see if 3D printed PET-G was a plausible option for something this small & with such minimal weight.

I went with a R9 Mini simply because it's both smaller & cheaper than any of the 2.4GHz receivers from FrSky, even if the long dipole antenna is a bit awkward on such a smol frame.

Dry weight is 77g, so notably up compared to the ~64g of the Babyhawk, but ain't it just the cutest?

hey,
Nice colors :)
I'm building a similar, albeit smaller, micro and have annissue mounting the Foxeer arrow

Did you 'just' zip tie the camera? No seat nothing? And how can you angle it?

Thank you!

It was just zip ties to the top plate, which gave it a bit of upward tilt. It's not a great solution, it needs longer standoffs to allow more than a very acute angle because the camera/VTX is just too big otherwise.

video?

Neat! I wonder if you could just zip tie the antennas along the arms for better protection. It's not carbon and should not affect the antenna performance.

I tried & it didn't make much of a difference, still sticks out ~1" at either end.

You've probably heard the term "Cinewhoop". Traditionally it's a 3" ducted quad capable of carrying a GoPro Hero7 Black at a low 10 degree angle. More recently the term "Cine" has been applied to a number of RTF quads ranging from 85mm to 3". They all focus on their HD capability, but none compare to the stabilization of Hypersmooth (only available on the Hero7 Black). This is what really offers that..
